New Seawall Construction for South Florida Waterfront Properties
If your property currently has no seawall, has an aging wall beyond repair, or you are building on a new waterfront lot — JKT Marine Construction installs new seawalls built specifically for South Florida's saltwater canals, Intracoastal Waterway, and open bay environments.
We design and build new seawalls using engineered plans, marine-grade materials, and full permitting through Palm Beach County, Broward County, SFWMD, FDEP, and the Army Corps of Engineers. Every installation is personally overseen by our ownership team from the first site visit through final inspection.
A properly engineered seawall protects your land, landscaping, pool, foundation, and property value for 30 to 50 years.
Warning Signs Your Seawall Needs Attention
Early repair is almost always more cost-effective than full replacement.
Cracks or fractures
Horizontal or wide cracks in wall panels are a serious structural warning sign requiring immediate assessment.
Leaning or bowing
Any visible lean toward the water means the tie rod or anchor system is compromised — it only gets worse.
Sinkholes behind the wall
Soft spots or depressions mean soil is washing through and the wall's foundation is being undermined.
Rust staining
Orange stains indicate corroding rebar inside the wall — concrete cancer that accelerates rapidly in saltwater.
Water seeping through
If water actively moves through your seawall during tidal movement, the wall's integrity is compromised.
Damaged seawall cap
A cracked or separating cap weakens the entire wall system and accelerates damage to everything below.
New Seawall Installation Services
We handle everything from new construction on vacant lots to full seawall replacement — all permits managed by our team, no subcontractors.
New Construction — Vacant Lots & New Builds
Installing a seawall before construction is always more cost-effective than retrofitting later. We work with builders, developers, and homeowners at the earliest project stage.
Full Seawall Replacement
When an existing seawall is beyond repair, we remove the failed wall and install a brand-new engineered seawall — concrete, vinyl, composite, or aluminum depending on your waterway.
Seawall Extension & Height Raising
Many older seawalls no longer meet current county elevation requirements. We raise seawalls to current standards — protecting against storm surge and king tides.
New Seawall with Integrated Cap
Every new seawall we install includes a properly formed and poured concrete cap engineered to current Palm Beach County and Broward County specifications.
Seawall Cap Repair & Replacement
One of the most cost-effective repairs. We replace deteriorating caps before they compromise the panels and tie rod system below.
Free Seawall Inspection
Free structural assessments for South Florida waterfront homeowners — written report with photos, risk scoring, and prioritized repair recommendations included.
Seawall Materials — Choosing the Right System
Not every waterway in South Florida is the same. Canal-front properties face different conditions than Intracoastal or open-bay properties. JKT Marine helps you choose the right material for your specific site.
Concrete Seawalls
The most common seawall type in South Florida. Precast concrete offers excellent strength and durability — ideal for Intracoastal properties and larger canals with heavy boat wake exposure.
Typical lifespan: 30–50 years
Vinyl Sheet Pile Seawalls
The most popular choice for residential canal properties. Completely corrosion-resistant, no rusting rebar, no spalling concrete. Lasts decades in South Florida's saltwater environment.
Typical lifespan: 40–50+ years
Composite Seawalls
Combines vinyl sheet piling with reinforced concrete caps and tieback systems — the best of both materials. Popular for Palm Beach County luxury properties where longevity and appearance both matter.
Typical lifespan: 50+ years
Aluminum Seawalls
The right choice when barge or crane access is not available. Lightweight, saltwater-resistant, and can be driven without heavy equipment — ideal for tight-access situations on narrow canals.
Typical lifespan: 25–40 years
The JKT Marine Seawall Installation Process
Building a new seawall in South Florida requires coordination with multiple regulatory agencies and precise engineering. Here is exactly what to expect when you work with JKT Marine.
Free On-Site Assessment
Our ownership team visits your property, evaluates waterway conditions, soil type, water depth, and tidal range, and discusses your goals and budget. No cost, no pressure.
Engineering and Design
We coordinate with a licensed marine engineer to develop seawall plans specific to your property — material selection, wall height, tieback design, and cap specifications.
Permit Filing — All Agencies
We file all required permits — Palm Beach County or Broward County Building, SFWMD, FDEP, and Army Corps of Engineers where required. Permitting typically takes 4 to 10 weeks.
Construction
Once permits are approved, our crew installs your new seawall. Most residential installations take 1 to 3 weeks of active construction depending on wall length and site conditions.
Final Inspection and Walkthrough
We manage all final county inspections and walk through the completed seawall with you before we leave. You receive a complete project record for your files.

Frequently Asked Questions — Seawall Installation in South Florida
How long does seawall installation take in Palm Beach County?
From first call to finished installation, plan on 8 to 14 weeks total. Permitting with Palm Beach County, SFWMD, and FDEP typically takes 4 to 10 weeks. Active construction takes 1 to 3 weeks depending on wall length. JKT Marine starts the permitting process immediately after your project is confirmed.
Do I need a permit to install a new seawall in Florida?
Yes — always. Every new seawall installation in Florida requires permits from your county building department, SFWMD, and often FDEP and the Army Corps of Engineers for navigable waterways. JKT Marine handles all permit applications, agency coordination, and final inspections on your behalf.
What is the best seawall material for South Florida?
Vinyl sheet pile is the most popular choice for residential canals in Palm Beach and Broward County because of its long lifespan, saltwater resistance, and competitive cost. Concrete is preferred for Intracoastal and high-traffic waterways where wave energy is greater. JKT Marine recommends the right material for your specific site during your free assessment.
How long does a new seawall last in South Florida?
A properly installed vinyl seawall lasts 40 to 50 years or more in South Florida. Concrete seawalls typically last 30 to 50 years. Lifespan depends on material choice, water conditions, and maintenance. Annual inspections significantly extend seawall life by catching small problems early.
Can you install a seawall if the bank has already eroded?
Yes. We frequently install seawalls on properties where significant erosion has already occurred. Depending on the extent of erosion, the process may include filling and compacting soil behind the new wall. We assess your bank condition during the free site visit and include any needed fill work in your quote.
How much does seawall installation cost in Palm Beach County?
A typical 80-foot residential canal seawall runs between $28,000 and $56,000 installed — including engineering, permitting, and all materials. Costs vary based on wall length, material type, water depth, and site conditions. JKT Marine provides free on-site estimates with a complete line-item quote before any work begins.
